1. Part 4: Smart Building Practices The practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life cycle. – This includes: Site design and management Resource efficiency Energy efficiency Water efficiency Indoor Air Quality Owner education 3rd Party verification Looks at the building “as a whole” rather that individual pieces that come together.

2. How do you IDENTIFY an Energy Efficient Home? Labels and Certificates The 3 rd party inspection importance Field Verification ENERGY STAR Products/Efficient Equipment?? Questions to ask the seller/builder

3. ENERGY STAR Products vs. ENERGY STAR Homes While Energy Efficient Home Programs will often require the use of ENERGY STAR certified lighting and appliances these alone do not equal qualified!!

4. ENERGY STAR Criteria for New Homes High performance windows Tight construction and ducts Effective insulation Efficient, properly installed equipment Water management Efficient lighting, water heating, appliances Ventilation, filtration, combustion safety Energy Modeling Third-party verification

5. The ENERGY STAR Home sample certificate

6. FIELD VERIFICATION ENERGY STAR qualified homes are inspected and tested by an independent Home Energy Rater to meet EPA's guidelines for energy efficiency. The Blower Door test measures how much air leaks out of a home’s envelope by studying at how much air must be removed from the home to reach a certain pressure level, thus testing the efficiency of the building envelope. Blower Door Test

7. FIELD VERIFICATION Duct Blaster Test Duct blaster test measures the leakiness of the home’s duct system. The average new American home duct system has about 20- 30% air leakage.

8. FIELD VERIFICATION Infrared Camera Diagnostics Many Home Energy Raters use infrared cameras to pinpoint areas where heat and cold can escape from a home so they can be sealed and properly insulated by the builder.

9. Third-Party Verification: Quality Assurance –HERS Raters inspect and/or test homes several times during the construction process –Often they model homes using software to determine the appropriate mix of measures needed to achieve a certain level of performance –Assist builder and subs –Not just another inspector Third-Party Verification 5

10. REM Rate Modeling software Use to “energy model” residential structures Provides annual energy use data

11. ENERGY STAR REM report Use in the Present Value of Future Savings equation

12. ENERGY STAR – Home Energy Raters and the HERS Index – Determine the HERS score of all homes they rate. – HERS Index A measure of a homes level of efficiency The lower the better Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home.

13. HERS Index can be used without ENERGY STAR qualification

15. How do you Identify a “Green” Home What is the difference? – Certified Green Buildings Have been certified to a national standard and third party verified to have complied with the provisions of that standard. – Green Features Are built in elements to any building that provide significant pay back. These features are typically advanced processes that are associated with a certification or that stand alone as significant building upgrades. – Green washing The act of misleading consumers regarding the benefits of a product, process or service. This may often be unintentional and in today’s “green marketing "arena we must be very carefully not to misinform the client.

16. Nationally Recognized Green Building Programs

17. What do all programs we will talk about today have in common? – 3 rd Party verified – Nationally or regionally recognized with a track record of success – Address multiple categories as part of the certification Resource and material efficiency Water efficiency Energy efficiency and environment Indoor air quality Site development Site location Building design – Point’s based rating system – bronze, silver, gold, etc.

18. LEED for Homes LEED – Leadership in Energy and Environmental Design – Developed by the USGBC (U.S. Green Building Council) – Offers certifications for homes, new buildings, developments, and existing buildings – LEED-certified buildings are designed to: Lower operating costs and increase asset value Reduce waste sent to landfills Conserve energy and water Be healthier and safer for occupants Reduce harmful greenhouse gas emissions Qualify for tax rebates, zoning allowances and other incentives in hundreds of cities

19. LEED cont… LEED – Leadership in Energy and Environmental Design – Offers a variety of professional credentials LEED for Homes Green Raters LEED Green Associate LEED AP – BD+C – Building Design + Construction – ID+C – Interior Design + Construction – HOMES – O+M – Operation + Maintenance (existing buildings) – ND - Neighborhood Development Educates and certifies a network of accredited green raters/verifiers that provides 3 rd party oversight on all LEED projects.

20. LEED sample certificate of approval

22. National Green Building Standard – NAHB Green – Created by the National Association of Homebuilders and the NAHB Research Center (now the Home Innovation Research Lab) – Developed the National Green Building Standard - used for rating new and remodeled single- and multifamily buildings as well as residential subdivisions. It is the first and only such residential green rating system to have earned the approval of the American National Standards Institute (ANSI).

40. The new code also includes the High Efficiency Residential Option (HERO) Appendix which delivers a 30% imenergy efficiency over the state’s curreprovement in minimum nt energy code. Completely voluntary and optional -- a great prescription for energy savings in all 3 NC climate zones. The Leading Edge -- 2012 NC HERO Code So how does this compare to ENERGY STAR? Will this make all of our NC Homes “Green”? New 2012 NC Code minimum: 15% better than 2009 New 2012 NC HERO Code Option: 30% better than 2009 ENERGY STAR v3 in 2012: Approx. 15-20% better than 2012 NC Code

47. Greening the MLS

48. What ELSE should we do with this information? Brokers need to fill this out! Greening the MLS

49. Why is a green MLS important – Assists appraisers in valuing high performance buildings and finding appropriate comps. – Assists consumers and agents in their search for existing high performance homes or buildings. – If properly done will prevent green-washing – Clearly defines what is green according to that region and help protect agents. – Assists in the valuation of “green” homes – How do we value “green” homes???? !@#$%^ Greening the MLS

50. Appraising Green Building

51. Green Appraising Methods Making Adjustments for Energy Efficiency – Matched Pairs – Present Value of future savings – GRM – Cost Approach – Marshall & Swift has a Green Section to the Residential Cost Handbook – Survey local builders and organizations. – Ask your peers – Web search engine – Many sources Adjustments for What? – Anything the market recognizes Energy Cost Savings HERS Rating Certification Solar Panels PV arrays Geo-thermal or other high efficiency HVAC system
